Cov txheej txheem ntau lawm
Kev lig kev cai, peb txoj kev tsim khoom yog feem ntau tus neeg sawv cev ntawm polypropylene ntau lawm. Hydrocarbon slurry los yog ncua kev kawm ntawv: Cov kua inert hydrocarbon diluent yog siv nyob rau hauv lub reactor hloov propylene mus rau lub catalyst, tshem tawm cua sov los ntawm lub system, deactivate / tshem tawm cov catalyst, thiab yaj cov atactic polymer. Qhov ntau ntawm cov qib uas tuaj yeem tsim tau yog tsawg heev. (Lub tshuab no tsis siv lawm).
Tej (los yog loj- ntim slurry): Cov kua propylene yog siv los ntawm cov kua dej inert hydrocarbon diluent. Lub polymer yog insoluble nyob rau hauv lub diluent thiab caij rau cov kua propylene. Qhov tshwm sim polymer yog rho tawm, thiab cov monomers tsis muaj kev cuam tshuam yog flashed tam sim ntawd.
Gas theem: Gaseous propylene yog siv nyob rau hauv kev sib cuag nrog ib tug khoom catalyst, uas ua rau ib tug fluidized txaj nruab nrab.
